Hf Spaces

hf-spaces

Generate AI content (images, video, audio, text) using HuggingFace Spaces and Inference Providers directly via gradio_client or MCP tools.

When MCP Tools Are Available

Check if relevant MCP tools exist (e.g. mcp__claude_ai_HF__gr1_z_image_turbo_generate for images, mcp__claude_ai_HF__gr2_ltx_2_turbo_generate_video for video). If so, use them directly — no script needed.

Batch with MCP tools: Call the tool multiple times (sequentially or in parallel tool calls) to generate multiple outputs.

When Writing Scripts

Use gradio_client for Spaces and huggingface_hub for Inference Providers.

Setup

uv init && uv add gradio_client huggingface_hub

Gradio Space Call

from gradio_client import Client

client = Client("owner/space-name")
result = client.predict(param1="value", param2="value", api_name="/endpoint")

HF Inference Provider Call

from huggingface_hub import InferenceClient

client = InferenceClient(provider="fal-ai")  # or replicate, together, etc.
image = client.text_to_image("a cat in space", model="black-forest-labs/FLUX.1-schnell")
image.save("output.png")

Batch Generation

from gradio_client import Client

client = Client("Tongyi-MAI/Z-Image-Turbo")
prompts = [f"A cute cat in style {i}" for i in range(10)]

for i, prompt in enumerate(prompts):
    result = client.predict(
        prompt=prompt,
        resolution="1024x1024 ( 1:1 )",
        random_seed=True,
        api_name="/generate",
    )
    images, seed_str, seed_int = result
    print(f"Generated image {i}: {images[0]['image']}")

Chaining Spaces

from gradio_client import Client

img_client = Client("Tongyi-MAI/Z-Image-Turbo")
vid_client = Client("alexnasa/ltx-2-TURBO")

result = img_client.predict(prompt="a sunset", resolution="1024x1024 ( 1:1 )", random_seed=True, api_name="/generate")
image_path = result[0][0]["image"]

video = vid_client.predict(first_frame=image_path, prompt="cinematic motion", duration=5, api_name="/generate_video")
print(f"Video: {video[0]}")

Finding Spaces

Semantic search (describe what you need): https://huggingface.co/api/spaces/semantic-search?q=generate+music+for+a+video&sdk=gradio&includeNonRunning=false

By category: https://huggingface.co/api/spaces/semantic-search?category=image-generation&sdk=gradio&includeNonRunning=false

Categories: image-generation | video-generation | text-generation | speech-synthesis | music-generation | voice-cloning | image-editing | background-removal | image-upscaling | ocr | style-transfer | image-captioning

Also use the mcp__claude_ai_HF__space_search tool if available.

Finding Models (Inference Providers)

https://huggingface.co/api/models?inference_provider=all&pipeline_tag=text-to-image

Pipeline tags: text-to-image | image-to-image | image-to-text | image-to-video | text-to-video | text-to-speech | automatic-speech-recognition

VLM/LLM models: https://router.huggingface.co/v1/models

Checking a Space's API

curl -s "https://<space-subdomain>.hf.space/gradio_api/openapi.json"

Replace <space-subdomain> with hyphenated lowercase (e.g., Tongyi-MAI/Z-Image-Turbo -> tongyi-mai-z-image-turbo). Spaces also have a "Use via API" link in the footer.

Handling Files

Gradio returns file dicts:

path = file.get("path") if isinstance(file, dict) else file

Authentication

Required for ZeroGPU Spaces and Inference Providers. Before making any authenticated call, check if a token is available:

python3 -c "from huggingface_hub import get_token; t = get_token(); print('HF token found' if t else 'NO TOKEN')"

If no token is found, ask the user to create one at: https://huggingface.co/settings/tokens/new?ownUserPermissions=inference.serverless.write&tokenType=fineGrained

Then have them run hf auth login or set HF_TOKEN in their environment.
